xxxii CLASSIFICATION. 



yellow ; a broad, rather indistinct, pale eyebrow ; cheeks, throat, and entire under surface of the 

 body pale-olive-shaded yellow, brightest on the lower chest and abdomen ; under surface of the 

 wings dark brown with the inner margins of the quills and the coverts white, the latter tinted 

 with yellow. Total length 3*5 inches, culmen 0*5, wing T9, tail 1*2, tarsus 05. This plumage 

 I should refer to the immature bird, possibly of both sexes. 



c. "Valencia, ?, August 1877." Differs from b only in the upper parts of the head and 

 neck being slightly more dusky, and in the bill being slightly longer and stronger. Culmen - 6. 

 This I consider to be the more advanced stage of the young bird, possibly of either sex. 



(1. "Dinagat, sex?, June 1877 : iris dark brown, bill black, legs dark brown." Upper parts 

 more ashy brown, with scarcely any shade of olive ; underparts, cheeks, and eyebrow ashy white ; 

 centre of the breast tinted with yellow. The feathers in this specimen are much worn. This 

 stage of plumage is possibly clue to its being a hen bird which has just gone through the labours 

 of incubation. 



e. " Surigao, 2, May 1877." Differs from a in the upper half of the head and back of the 

 neck being ashy, not shaded with olive, the sides of the head paler and greyer, and the throat 

 ashy white. This I presume to be the female in fully adult plumage. It agrees well with the 

 adult female which I previously described and figured from the collection made by Dr. Steere 

 in Luzon. 



f. " Valencia, $, August 1877." Similar to the last, excepting that the back of the neck 

 and sides of the head are shaded with olive, and a few feathers on the front of the chest tinged 

 with scarlet. This plumage I presume to belong to the young male or adult male in full moult. 



(j. "Puerto Princesa, ?, 27th December 1877." Similar to «, excepting that some of the 

 feathers of the upper back and scapulars are shaded with rufous; margins of the wing-feathers 

 more strongly shaded with rufous ; centre of the chest and abdomen darker, and brighter yellow. 



//. " Dinagat, cf, June 1877." Perfectly similar in plumage to the last. Males, probably 

 young. 



I consider that e is the full adult female; d, adult female after breeding; a, b, and c, young, 

 possibly of either sex ; f, g, and h, young males. 



In fully plumaged adult males the abdomen and under tail-coverts are of a dusky-olive. 

 These parts are generally shaded or mottled with olive-yellow, which I believe to be due 

 to the last remains or approach of the moult : in some of these specimens the crown is more 

 or less strongly shaded with fiery copper ; and in such specimens the lower back and upper tail- 

 coverts are generally more strongly shaded with lilac. 



In two specimens labelled "tf, Puerto Princesa, January 1878," in partial moult, the crown 

 and nape are ashy brown, and the back and scapulars are mottled with that colour ; the sides of 

 the throat and the sides of the upper chest mottled with ashy white, and the abdomen and under 

 tail-coverts are bright olive-yellow. In these specimens the metallic feathers which mottle the 

 crown are of a fiery copper-colour, and the lower back and upper tail-coverts are very strongly 

 glossed with lilac, but not to an equal extent ; and in one specimen the throat is rather bluer 

 than in the other.
